Key Not for Resale ISO 1701-2:2004(E) 3.2 Milling operations Milling is a machining operation, which consists of removing material by means of a rotary tool called a “milling cutter” of which there is several different types The usual operations of milling can be divided into three categories: slab milling operations (see Figure 3); face milling operations (see Figure 4); end milling operations (see Figure 5) Figure — Slab milling operation Figure — Face milling operation Figure — End milling operation 3.3 Description of machines In milling machines with table of variable height with vertical spindle, the base-plate is rigidly fixed to the column (see Figures and 2) In this type of machine, the cutting movement is given by the spindle, the axis of which is vertical The feed movements are as follows: The X axis of motion constitutes the longitudinal movement of the table The Y axis of motion constitutes the vertical movement of the table Copyright International Organization for Standardization Reproduced by IHS under license with ISO No reproduction or networking permitted without license from IHS `,,,,,,-`-`,,`,,`,`,,` -
